Question

Three numbers which are co-prime to each other are such that the product of the first two is 551 and that of the last two is 1073. The sum of the three numbers is: 75

Answer 1

Answer:

Step-by-step explanation:Hey mate

Since the numbers are co-prime, they contain only 1 as the common factor.

Also, the given two products have the middle number in common.

So, middle number = H.C.F. of 551 and 1073 = 29;

First number =

Third number =

∴ Required sum = (19 + 29 + 37) = 85.

Answer 2

Given :

• 3 numbers which are co-prime to each other such that the product of the 1st two numbers is 551 and that of the last 2 is 1073.

To find :

• The sum of 3 numbers?

Calculations :

★ Taking HCF (Higest common factor) for 551 and 1073.

= HCF = 29 ---(1)

★ Dividing the first number and last number by the 29, we get:

= 551/29

= 19 ---(2)

= 1073/29

= 37 ---(3)

★ As per the last case, sum of three numbers, we get:

= 29 + 19 + 37

= 85

★ Therefore, the sum of three numbers is equal to 85.
